【摘要】：对中国石化扬子石油化工有限公司2.0 Mt/a渣油加氢装置第一周期的运行情况及存在的问题进行了分析,并提出处理措施。运行结果表明:在处理量为设计负荷的104%的情况下,渣油加氢装置的各项技术指标均满足设计要求;FZC系列催化剂具有较高的脱杂质活性和加氢活性,加氢渣油的密度、硫含量、氮含量、残炭和金属含量均达到或优于设计值,是优质的催化裂化原料。针对装置原料劣质化、热高压分离器气体夹带重烃、循环氢脱硫塔发泡及高压换热器结垢等情况,采取相应的对策,取得了较好的效果,初步解决了装置高苛刻度运行过程中存在的问题。
[Abstract]:The operation and existing problems of the 2. 0 Mt/a residue hydrogenation unit in Yangzi Petrochemical Co., Ltd., Sinopec were analyzed in the first cycle. The operation results show that each technical index of the residue hydrogenation unit meets the design requirements when the treatment capacity is 104% of the design load. FZC series catalysts have high deimpurity activity and hydrogenation activity, and the density, sulfur content, nitrogen content, carbon residue and metal content of hydrogenation residua are up to or superior to the design value. It is a high quality FCC feedstock. In view of the deterioration of feedstock, the entrainment of heavy hydrocarbon by hot and high pressure separator gas, the foaming of circulating hydrogen desulfurization tower and the scaling of high pressure heat exchanger, the corresponding countermeasures are taken. Good results have been obtained and the problems existing in the operation process of the device with high severity have been preliminarily solved.
